Today NASA confirmed that it has testify of liquid H2O flowing on Mars. The novel testify consists of hydrated salts discovered on downhill streaks on the side of Hale Crater. It is believed that the hydrated salts would lower the freezing indicate of liquid brine in addition to that the streaks on the crater are thence testify of the shallow subsurface menses of briny water.
Entirely past times coincidence the European Space Agency has collaborated alongside CartoDB to release a novel map of Mars. This novel floor map shows the iv possible landing sites for the ExoMars 2018 Mission. ESA's ExoMars programme volition province a rover on the surface of Mars to search for signs of past times in addition to introduce life.
Where on Mars? is a superbly crafted floor map which explains the diverse criteria beingness used to alternative the perfect landing site for the rover. The map includes a pose out of dissimilar map views of the cerise planet. Using the forrad in addition to dorsum buttons on the map you lot tin sack progress through the dissimilar map layers to larn to a greater extent than close how the end landing site volition hold upward chosen.
An altimetry map layer provides a rut map persuasion of pinnacle on Mars. Because the lander requires a parachute to province on Mars the landing site must hold upward lower than -2km to reach the parachute plenty fourth dimension to ho-hum the lander down. If you lot mouse-over the pinnacle map a window volition opened upward to say you lot when you lot are over an surface area also elevated to hold upward a potential landing site.
Because the ExoMars Rover is solar powered the landing site must also hold upward inside a certainly ring of latitude straddling the equator. As you lot progress through the floor map this ring of latitude is highlighted on the map. Again if you lot mouse-over the map an data window volition opened upward to demo you lot when you lot are exterior this latitude band.
As you lot progress you lot tin sack larn to a greater extent than close the geological constraints for the perfect landing site, the landing eclipse (the probability of landing inside a given distance of the target site) in addition to some of the of import locations roughly the potential landing sites.
